Description

[Detailed description of the invention] <<Industrial application>> This invention relates to a container with a cap in which a cap is elastically fitted to the container body in a vertically removable manner, and more specifically, This invention relates to a container with a cap, which is provided with a flexible ring and which is detachable by pushing the flexible ring horizontally inward.

<<Prior Art>> Conventionally, as this type of container with a cap, those shown in Japanese Unexamined Utility Model Publications No. 118647/1982 and No. 62044 of 1988 have been known.

The former type of container with a cap has a cylindrical flexible ring loosely fitted to the peripheral wall hanging down from the inside of the top plate of the cap, while an inclined surface is formed on the peripheral edge of the shoulder of the container body, and the cap is When the flexible ring is fitted into the container body, the lower end of the flexible ring is located close to the inclined surface, and when the flexible ring is deformed inward from this state, the lower end of the flexible ring is positioned close to the inclined surface. The cap, which is loosely fitted in the flexible ring, rises along the inclined surface of the flexible ring, thereby allowing the cap, which is loosely fitted in the flexible ring, to rise and be separated from the container body.

However, with this container with a cap, it is necessary to form an inclined surface on the peripheral edge of the shoulder of the container body, and the container shape is limited to a relatively narrow range, making it difficult to apply it to various types of container bodies. There is a problem.

In the latter container with a cap, the cap is composed of two members, an upper member and a lower member, and a flexible ring is loosely fitted between the upper and lower members. This flexible ring is provided with a push button that projects outward from the peripheral wall of the cap, and is integrally formed with projecting pieces that extend obliquely inward above and below the push button. and,
The upper end of the upwardly extending protrusion abuts the lower surface of the top plate of the cap, and the lower end of the downwardly extending protrusion abuts the upper surface of the shoulder of the container body.

In this container with a cap, when the push button of the flexible ring is pushed inward from the state where the cap is fitted into the container body, the protrusions formed at the top and bottom of the push button stand up vertically, pushing the cap upward. Then, the fitting from the container body is released.

[Problems that the invention aims to solve] However, in the latter type of container with a cap, the flexible ring is integrally assembled with the upper and lower members that make up the cap, so the structure of the cap is limited, and various types are available. cannot be easily applied to the cap. In addition, in order for the lower protrusion to stand up vertically when the push button is pushed inward, a step is required on the upper surface of the shoulder of the container body to prevent the lower protrusion from sliding. In the case of the above-mentioned container with a cap, the step is the intersection of the horizontal surface of the upper surface of the shoulder and the sloped surface, and since it is necessary to provide such a step in the container body, there are restrictions on the shape of the container body. . Furthermore, since the cap is composed of two members, an upper member and a lower member, separate molding molds are required, and it is troublesome to assemble the flexible ring to the upper and lower members, which increases costs. There is a problem that has become unavoidable.

The present invention was developed in view of the above-mentioned problems.The purpose of this invention is to create a container body with a smooth upper surface of the shoulder without applying special processing such as sloped surfaces or steps to the shoulder of the container body. To provide a container with a cap, which can be applied to most conventional caps without special processing, and which can be formed at low cost with a simple structure. .

<Means for Solving the Problems> In order to achieve the above object, in this invention, a cap is elastically fitted to the container body in a vertically removable manner, a flexible ring is attached to the cap,
In a container with a cap, in which the cap is detachable from the container body by pushing the flexible ring in a horizontal direction, an intermediate frame that fits loosely into the neck portion of the container body in close proximity to the lower surface of the cap; A flanged corner portion is provided on the inner periphery of the lower surface of the inner frame, and the flexible ring is provided below the corner portion, and the lower surface of the flexible ring is made a smooth surface to form a shoulder portion of the container body. A push-up plate extending diagonally upward inward is integrally attached to the inner surface of the flexible ring, and the upper end of the push-up plate is attached to the flanged corner of the middle frame. They are brought into contact with each other.

<<Operation>> Since the container with a cap of the present invention is constructed as described above, when the flexible ring is pushed inward from the state where the cap is fitted into the container main body, the flexible ring will fit into the shoulder of the container main body. The upper surface slides and bends inward, and the push-up plate at the bent part stands up vertically, lifting the middle frame. As the middle frame rises, it pushes up the lower end of the cap, so that the cap separates from the container body.

<<Embodiments>> Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

First, the first part of the present invention shown in Figures 1 and 2.
In the container with a cap according to the embodiment, the container 1 is constructed by incorporating a flexible ring 8 made of synthetic resin and an inner frame 10 into a shoulder portion 4 of a main body portion of a container body 2 in a superposed state.

The container body 2 is formed with an inclined part 5 which is inclined upward from the center of the shoulder part 4 of the cylindrical main body part 3, and furthermore, an opening neck part 6 is provided protruding from the center of the inclined surface 5. An annular locking protrusion 7 having a substantially trapezoidal cross section is integrally formed on the outer periphery of the tip of the open neck portion 6 .

The flexible ring 8 has a substantially semi-elliptical cross section, and has a plurality of push-up plates 9 projecting obliquely upward from its inner periphery. The ax push-up plate 9 is formed thin so that it can be easily bent using the base as a fulcrum, and the tip is thickened to make it easier to push up the middle frame 10. Also,
The flexible ring 8 has an outer diameter larger than the outer diameter of the container body 3, an inner diameter smaller than the outer diameter of the container body 3, and is placed on the shoulder 4 of the container body.

The inner frame 10 has a disc shape with an inner diameter slightly larger than the outer diameter of the neck portion 6 of the container, but smaller than the outer diameter of the locking protrusion 7, and an outer diameter slightly smaller than the outer diameter of the container body 3. However, the lower surface is formed into an L-shaped cross section with a flange 11 inside.

This inner frame 10 has, for example, a vertical cut, and is assembled into the container by press-fitting the cut into the neck portion 6 of the container and superimposed on the flexible ring 8.

On the other hand, the cap 12 is a synthetic resin molded product with sufficient rigidity, and includes a disk-shaped ceiling surface 13 with a diameter approximately the same as the outer diameter of the container body 3, and a cylindrical peripheral wall portion 14 that hangs down from the periphery of this ceiling surface 13. And this peripheral wall part 1
4 has a plurality of flexible claw pieces 15 formed by drilling slits in a cylindrical part that hangs down from the lower surface of the ceiling surface 13. A cutout surface 16 is formed by cutting out a portion of the inner circumferential side of the lower end of the peripheral wall portion 14, and the flexible claw piece 15 has a substantially trapezoidal locking protrusion 17 on the inner circumferential side.

In the state shown in FIG. 2A, the cap 12 is completely fitted into the container 1. That is, the locking protrusion 17 provided on the flexible claw piece 15 on the cap 12 side
The seal 18 of the cap is in contact with the upper surface of the neck of the container by elastically riding over the locking protrusion 7 provided on the side neck, and the cap 12 is positioned in the correct closed position with respect to the container 1. In this state, the cutout surface 16 of the peripheral wall of the cap 12 and the lower end surface of the flexible claw piece 15 are close to or in contact with the upper surface of the inner frame 10 of the container, and the flexible The sex ring 8 is in contact with the lower surface of the middle frame 10,
Further, a push-up plate 9 raised obliquely upward from the inner circumferential portion of the flexible ring is also in contact with a corner of a flange forming the lower surface of the middle frame 10.

To remove the cap 12 from the above condition,
As shown in FIG. 2B, the flexible ring 8 is pressed inward with a finger. Due to this pressing operation, the push-up plate 9 raised obliquely upward from the flexible ring 8 is bent with its base as a fulcrum, and its tip, which is the point of action, is pressed against the corner of the lower flange of the middle frame 10. Therefore, the rising angle of the push-up plate 9 approaches vertical depending on the amount of push-in of the flexible ring 8. Therefore, the force pushing up the middle frame 10 increases, and the middle frame 10 is pushed upward, so that the cap 12 is pushed upward via the middle frame 10. Therefore, the flexible claw piece 1 provided on the cap 12
The locking protrusion 17 of 5 elastically rides over the locking protrusion 7 of the container 1, and the cap 12 is removed from the container 1.

Figure 3 shows a second embodiment in which the present invention is applied to liquid containers for perfumes, colognes, etc. Figure 3A shows the cap fully closed, and Figure 3B shows the cap when it is removed. The operating state is synthesized.

Note that the same reference numerals will be used for the same parts as in the first embodiment, and detailed explanations will be omitted.

In this embodiment, the container 1 has a recessed groove 19 formed on the outer periphery of the neck portion 6, and an inner stopper 20 that fits into and is locked in the recessed groove 19. The inner stopper 20 has a cylindrical portion 21 that fits into the inner surface of the neck portion 6 of the container 1 and has a bottom surface at the end thereof, and a locking protrusion 22 is provided protruding from the inner periphery of the cylindrical portion 21. Further, a small circular hole 23 is bored in the center of the bottom surface of the cylindrical portion 21.

On the other hand, the cap 12 has a cylindrical peripheral wall surface 14 that hangs down from the periphery of the ceiling surface 13, and a cylindrical stopper 25 having a locking protrusion 24 protruding from the center of the lower surface of the ceiling surface 13.

In the state shown in FIG. 3A, the locking protrusion 24 of the cap 12 is completely fitted over the locking protrusion 22 of the container 1, and the cap 12 is positioned in the correct closed position with respect to the container 1. There is. In this state, the cutout surface 16 of the peripheral wall of the cap 12 is close to or in contact with the upper surface of the inner frame 10 of the container 1, and the flexible ring 8 incorporated in the shoulder 4 of the container body 3 is placed on the lower surface of the inner frame. The push-up plate 9, which is raised diagonally upward from the inner circumferential portion of the flexible ring 8, also abuts on a flange corner formed by the lower surface of the middle frame 10.

To remove the cap 12 from the above condition, press the flexible ring 8 inward with your finger as shown in FIG. 3B. Due to this pressing operation, the push-up plate 9 is bent with its base as a fulcrum, and its tip, which is the point of action, is pressed against the corner of the lower flange of the middle frame 10, so that the rising angle of the push-up plate 9 is flexible. It approaches verticality depending on the amount of pushing of the ring 8. Therefore, the force that pushes up the middle frame 10 increases, and the cap 12 is pushed upward via the middle frame 10. Therefore, the locking protrusion 24 of the cylindrical stopper 25 provided on the cap 12 rides over the locking protrusion 22 provided on the inner stopper 20 of the container 1, and the cap 12 is removed from the container 1.

<<Effects of the invention>> As described above, in the container with a cap according to the present invention, the inner frame is fitted loosely into the neck of the container body below the cap, the flexible ring is disposed below the inner frame, and the container is flexible. When the flexible ring is pushed inward, the middle frame is pushed up, and the middle frame then acts on the lower end of the cap to raise the cap. The structure of the present invention can be applied to release the fitting.

In addition, the flexible ring in the container with a cap of the present invention is placed on the shoulder of the container body with its lower surface being a smooth surface, and simply slides on the upper surface of the shoulder. It does not require special processing such as adding inclined surfaces, and can be widely applied to general container bodies.

Furthermore, in the container with a cap of the present invention, in addition to the cap, the inner frame and flexible ring are separately molded and simply stacked vertically on the neck of the container body, making molding and assembly easy. Cost reduction can be achieved.
